parental test

The Horizon parental test is a screening test of up to 274 genetic condition, and provides valuable information on future parents likelihood of having a child with a genetic condition.

Most people are carriers of at least four to six genetic conditions, but most carriers are healthy because the other copy of the gene works normally. However, carrier couples are at the increased likelihood to have a child with a genetic condition, so knowing your status allows parents-to-be to make more informed reproductive decisions.

If you and your partner are both carriers of the same condition, you have a 1-in-4, or 25%, chance with each pregnancy of having a child affected with the condition. If you as a woman is a carrier of an X-linked condition, you have a 50 percent chance with each pregnancy of passing the gene mutation to your child. If the child is a boy, and he inherits the mutation, he will be affected with the condition.

Autosomal recessive inheritance

Both parents-to-be must be carriers of the same genetic condition to pass it on to their future child. This is known as autosomal recessive inheritance.

If both the future father and mother carry the same genetic condition, there is a 25 percent likelihood that each of their future children will be affected (regardless of gender). Meanwhile, the likelihood that the future child is just a carrier, or is completely healthy, is 75 percent.

Likelihood that baby is affected when both mother and father are carriers



Unaffected carrier




X-linked inheritance

If a woman is a carrier of an X-linked condition, she has a 1-in-2, or 50%, chance with each pregnancy of passing the gene mutation to her child. If the child is a boy, and he inherits the mutation, he will be affected with the condition

Likelihood that baby is affected when only mother is a carrier



50% unaffected

50% non-carrier

50% affected

50% carrier

Who is the Horizon test suitable for?

The Horizon test is suitable for all couples who want to gain valuable insight into their likelihood of passing on genetic conditions to their future children. The test screens for cystic fibrosis, which is very common, spinal muscular atrophy or Duchenne / Becker muscular dystrophy – and many, many more.

It is possible to screen for a total of 274 genetic conditions.

Horizon can be performed at any time before or during pregnancy. Some people may want to know their carrier status before pregnancy to inform reproductive decisions.

You must be at least 18 to have the Horizon test performed.

The benefit of learning more through Horizon

If you and your partner are carriers, it is possible to establish whether your little one is affected through a placenta biopsy or amniocentesis.

If you are planning your pregnancy (and you know your carrier status), you can seek help to avoid having a baby who will be affected by any condition you or your partner might carry.

Horizon needs only be performed once in a lifetime.
